Abstract
An aerosol generating system includes a container (150) housing an aerosol generating substrate and a product identifying compound (155) associated with the container (150). The system further includes an electronic article (100) configured to receive the container (150). The electronic article (100) includes control electronics (200) and an electrochemical sensor switch (10, 20) operably coupled to the control electronics (200). The electrochemical switch (10, 20) is configured to change from a first state to a second state when the product identifying compound (155) interacts with the electrochemical sensor. The electrochemical sensor switch (10, 20) has a different conductivity in the first state than in the second state. The control electronics (200) are configured to cause the device to generate an aerosol from the aerosol generating substrate when the electrochemical sensor switch (10, 20) changes states due to interaction with the product identifying compound (155).
